Q. From or to HMailServer version 4.4.1.

R. You have to add prefix and separator manually because 4.4.1 doesn't

honor the NAMESPACE imap command.

Example for host1:

Explanations:
|
||||
|
||||
If you're using a different language in Gmail you might adapt
|
||||
this example with the folder name translated, an example in French:
|
||||
--ssl2 is mandatory since Gmail only supports imap ssl connections.
|
||||
|
||||
imapsync ...
|
||||
--regextrans2 "s,^Messages envoy&AOk-s$,[Gmail]/Messages envoy&AOk-s," \
|
||||
--exitwhenover 500000000 option is here to avoid locking when
|
||||
transfers exceed maximum limit.
|
||||
See http://support.google.com/a/bin/answer.py?hl=en&answer=1071518
|
||||
--exitwhenover is not mandatory in the sense you may be able to
|
||||
use an upper value than 500 MB without disconnections; I don't
|
||||
know the hard value, it seems to vary, so just have some tries
|
||||
and report me what you discover in case you detect something.
|
||||
|
||||
The --addheader option is there because "Sent" folder messages
|
||||
sometimes lack the "Message-Id" header needed by imapsync
|
||||
to identify messages (only when --useuid is not used).
|
||||
So option --addheader adds a "Message-Id" header.
|
||||
|
||||
You can add --folder "INBOX.Sent" in the example in case
|
||||
you want to sync only the "Sent" folder.
|
||||
|
||||
The "All Mail" archive pseudo-folder should be updated automaticaly.

|

sometimes lack the "Message-Id:" and "Received:" headers needed
|
||||
by imapsync to identify messages (only when --useuid is not used).
|
||||
So option --addheader adds a "Message-Id" header consiting fo
|
||||
the imap UID of the message on the host1 folder, like
|
||||
"Message-Id: 12345@imapsync".
|
||||
|
||||
--exclude "\[Gmail\]$" is there to avoid a small examine/select error:

--ssl1 is mandatory since Gmail only supports imap ssl connections.

--exitwhenover is not mandatory in the sense you may be able to

use an upper value than 2.5 GB without disconnections; I don't

know the hard value, it seems to vary, so just have some tries

and report me what you discover in case you detect something.
|
||||
|
||||
--useheader="X-Gmail-Received" --useheader "Message-Id" are not
|
||||
mandatory. I use them because I found (several years ago, it may
|
||||
have changed) that Gmail always adds a different header
|
||||
"X-Gmail-Received:" to all messages it gets. So the identification
|
||||
by imapsync can not fall using this header. "Message-Id" is there
|
||||
for safety about this Gmail rule.

|
||||
|
||||
--skipcrossduplicates is optional but it can save Gigabytes of hard
|
||||
disk memory. Within imap protocol, Gmail presents Gmail labels as
|
||||
folders so a message labeled "Work" "ProjectX" "Urgent" ends up
|
||||
in three different imap folders "Work" "ProjectX" and "Urgent"
|
||||
after an imap sync. --skipcrossduplicates prevent this behavior.
|
||||
|
||||
An issue with --skipcrossduplicates is that the first label synced
|
||||
by imapsync goes to its corresponding folder and other labels are
|
||||
ignored. This way, at least you can choose what labels have the
|
||||
priority by using the --folderfirst option. For example
|
||||
--folderfirst "Work" will sync messages labeled "Work" before
|
||||
messages labeled "CanWait" or "Urgent". By default imapsync
|
||||
syncs folders (Gmail labels) using the classical alphanumeric order.
|
||||
|
||||
--folderlast "CanWait" will sync only messages that have the
|
||||
label CanWait and only it.
|
||||
|
||||
--folderlast "[Gmail]/All Mail", in conjonction with option
|
||||
--skipcrossduplicates, will only put in "[Gmail]/All Mail"
|
||||
the messages that are not labeled at all.
